A cliff-top dune is a type of coastal geological formation that occurs at the edge of a cliff or elevated area, where sand accumulates to form a dune near the coastline. These dunes can be shaped by wind and wave action, and they often serve as a buffer between the ocean and the land, protecting the cliff and any structures above from erosion.
